Bug description:
from 3.10, io.text_encoding may return 'locale' if encoding is None, and the function open can support it well, like:
>>> open('/dev/null',encoding=io.text_encoding(None))
<_io.TextIOWrapper name='/dev/null' mode='r' encoding='UTF-8'>but codes.open raised an error when i was doing this:
>>> codecs.open('/dev/null',encoding=io.text_encoding(None))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<frozen codecs>", line 910, in open
LookupError: unknown encoding: locale
>>> codecs.open('/dev/null',encoding='locale')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<frozen codecs>", line 910, in open
LookupError: unknown encoding: localeand codes.open can deal None correctly:
>>> codecs.open('/dev/null',encoding=None)
